BQ2054SN Description

Short technical summary and product information.

The Texas Instruments BQ2054SN is a Lithium Ion Fast-Charge IC engineered to optimize the charging process for Li-Ion battery chemistries. It utilizes a flexible pulse-width modulation regulator to control both voltage and current during charging, ensuring efficient power conversion with minimal dissipation.

 

Key features include voltage-regulated, current-limited charging, with fast charge termination based on a selectable minimum current. Safety is enhanced by a backup termination on maximum time and continuous qualification by temperature and voltage limits. The device measures battery temperature using an external thermistor for charge qualification and provides low-current conditioning for batteries below a low-voltage threshold.

 

Designed for high-efficiency switch-mode power conversion, the BQ2054SN operates within a supply voltage range of up to 5.5V and an ambient temperature range of -20°C to 70°C. It is housed in a 16-SOIC package suitable for surface mounting. The IC also provides direct LED control outputs to display charge status and fault conditions, aiding in accurate determination of battery and charge system conditions.
